Sorry Dave, I didn't see you replied...
One of my biggest complaints is that they put the man doors in to swing out. I don't hover contractors that I hire, but this is one that I wish I had been there to have them do different. I even considered flipping them after the fact, but didn't. Also, the concrete work...it is "flat" in the fact that I didn't want any slope, but they did get some low spots. It's a garage, and not a big deal, but I must have heard him say a half dozen times about how good a concrete guy he is.
The other stuff was a bit of an inconvenience when I was finishing the inside...everything is square and plumb (very much so actually) but with it being a pole style construction, they used 16' girts, and set the intermediate posts "close enough" to 8'. Because of the way they built it, it made absolutely no difference, but I had to be aware of it when I finished the inside.
No doubt that the delay didn't hurt, but the roller/compactor and the size of lifts they put in was equal to what we would spec out on pretty much all of our construction projects. But like you said, it didn't hurt.
